IMPROVEMENT IN MODE 0F,F ORMING 'UMBRELLA-HANDEES FROM PLASTIU MA- TERIAL.

To ullwhcm it may conce-rn.-

Be it known that I, LEVI CHAPMAN, of the city and State of New York, have'invented an Improvement in Handles for- Umbrellas, 85e.; and the following' is hereby declaredto be a correct description of the same. i

In 'Letters Patent granted to mc May'25, 1869, No. 90,498, a handle is described, inl which a plastic composition is pressed around a tubular socket for the cane or stick.

In'testing the said invention and making experiments I have discovered that, when a plastic composition, such as before described, is pressed directly upon a wooden. stick, rod, or cane, the wood is liable to he injured bythe heat and pressure, and either contracts and becomes loose, or expands and renders the handle imperfect, vespecially where thin material Where 'a metal screw is inserted in the plastic composition, and projects beyond the handle to be screwed into the wood, the wood` is liable to be ,wrenched and broken, besides which the handle, being@ solid or nearly so, contains a larger amount of the plastic material.

Where there is a hollow socket formed in the handle to receive the stick, cane, or tube of the umbrella or-paiasol, or where the .plastic material is pressed .upon the metal ot' the handle or tube itself, the plastic material is sustained, and there is no more thereot made use4 of than is required for the particular shape and size of the handle.

My present invention is an improvement upon the mode ot' manufacturing the said handles, whereby they can be made strong and reliable, but are more easily adapted to the various characters of sticks, canes, tubes, or other' articles to which said handles are to be applied.

The object ot'iny present )invention ,is to form a socket in the handle without the use of a rigid metallic tube, so that, if it becomes important to enlarge the tubular socket, the same can be easily bored out, andthe handlecau be thn's easily adapted to metallic or wooden umbrella sticks, canes, or other articles.

In manufacturing handles ot' the plastic composition, such as shell-ac and sawdust intimately ground,

considerable pressureis employed in-moldi-ng themass around which the plastic material can be pressed, and

then the core can be removed with ease, either partially or entirely, and the socket will `be ready for the reception of the stick, cane, orother article.

I make the core ol'a tube of paper, mnslin, or other flexible material, and the same may either be sniiciently stift' and rigid to withstand the pressure ofthe plastic material, or the tube may betilled with a core of iron or otherA material that can easily'be removed, leaving the paper lining within the handle, and the Asame may be removed, it desired, by boring out the socket or otherwise. v

For a handle for a metallic tube or stick I find that a metal core, greased and wrapped with a piece of paperor tin-foil, willv answer the best, as the metal core can be easily removed.

For wooden canes oisticks the lining of paper withiu the socket is advantageous, as-glue will adhere thereto when used to cement in the said wooden cane or stick. f

In the drawing I have represented a longitudinal,

section of the handle;-

a being the core, formed of a tube of paper or other iiexible material, and j b, the material pressed in a plastic state around such core.

I claim as my invention- The handle made of plastic material around a lining of paper or other flexible material, substantially as speciiied.
